BACKGROUND

1. Technical Field

The present teaching relates to methods, systems and programming for Internet Service. More particularly, the present teaching relates to methods, systems, and programming for identifying and delivering content.

2. Discussion of Technical Background

With the quickly-growing adoption of smart phones and mobile tablet computers among consumers of the Internet, more and more consumers are accessing content on such mobile devices. Generally speaking, mobile devices, when compared to, for example, a desktop computer, tend to be more limited in certain aspects such as bandwidth and display size. Consequently, certain content, such as a web page intended to be viewed on a desktop computer, is not easily viewable or navigable on a mobile platform. To address this problem, many content providers have developed, for example, “mobile-specific” web sites which present the requested content in a way that is smaller in size and more easily readable and navigable by a user. The user seeking this content still uses the same URL but the site detects the platform and redirects to a platform-specific page. More recently, as more and more users are accessing content on mobile platforms, there are more and more content providers that are choosing to develop and maintain “mobile-specific” sites exclusively. However, when such mobile-specific content pages are viewed on a platform such as a desktop computer, the minimalist design for a mobile device does not provide a user with an experience that has come to be expected when accessing a content page on, for example, a desktop computer. In addition, with the larger browser display sizes that are typically associated with other devices such as desktop computers, there is an opportunity to include additional content that a user might find helpful when viewing the requested content page.

Hence, existing solutions to displaying mobile-specific content pages, do not address the issue of providing the same content to a user of a desktop computer in a way that is generally expected by users when accessing content pages. Therefore, there is a need to develop techniques to enrich mobile-specific content pages for display on a larger platform in order to provide the user with additional content and an experience that is superior to that which is available on a mobile-specific page.

SUMMARY

The present teaching relates to methods, systems and programming for Internet Service. More particularly, the present teaching relates to methods, systems, and programming for identifying and delivering content.

In one example, a method, implemented on at least one machine each having at least one processor, storage, and a communication platform connected to a network for providing content is presented. A request for content is received from a user. One or more parameters associated with a first platform on which the requested content is to be presented are obtained. A plurality pieces of addition content are obtained based on the requested content or information associated with the user. Each piece of the addition content is associated with a user engagement metric. A layout of an enriched content page is determined based on the one or more parameters associated with the first platform. The layout of the enriched content page includes one or more slots for presenting content. One or more pieces of the additional content are assigned to the one or more slots based on the user engagement metric. The enriched content page including the requested content and the one or more pieces of the additional content is transmitted to the first platform.

In a different example, a system having at least one processor, storage, and a communication platform connected to a network for providing content is presented. The system includes a request handling unit, a parameter handing unit, an enriched content generator, a content page generator, and a transmitting unit. The request handling unit is configured to receive a request for content from a user. The parameter handing unit is configured to obtain one or more parameters associated with a first platform on which the requested content is to be presented. The enriched content generator is configured to obtain a plurality pieces of addition content based on the requested content or information associated with the user. Each piece of the addition content is associated with a user engagement metric. The content page generator is configured to determine a layout of an enriched content page based on the one or more parameters associated with the first platform, the layout of the enriched content page including one or more slots for presenting content, and to assign one or more pieces of the additional content to the one or more slots based on the user engagement metric. The transmitting unit is configured to transmit the enriched content page including the requested content and the one or more pieces of the additional content to the first platform.

Other concepts relate to software for providing content. A software product, in accord with this concept, includes at least one non-transitory machine-readable medium and information carried by the medium. The information carried by the medium may be executable program code data regarding parameters in association with a request or operational parameters, such as information related to a user, a request, or a social group, etc.

In one example, a non-transitory machine readable medium having information recorded thereon for providing content is presented. The recorded information, when read by the machine, causes the machine to perform a series of processes. A request for content is received from a user. One or more parameters associated with a first platform on which the requested content is to be presented are obtained. A plurality pieces of addition content are obtained based on the requested content or information associated with the user. Each piece of the addition content is associated with a user engagement metric. A layout of an enriched content page is determined based on the one or more parameters associated with the first platform. The layout of the enriched content page includes one or more slots for presenting content. One or more pieces of the additional content are assigned to the one or more slots based on the user engagement metric. The enriched content page including the requested content and the one or more pieces of the additional content is transmitted to the first platform.

DETAILED DESCRIPTION

In the following detailed description, numerous specific details are set forth by way of examples in order to provide a thorough understanding of the relevant teachings. However, it should be apparent to those skilled in the art that the present teachings may be practiced without such details. In other instances, well known methods, procedures, components, and/or circuitry have been described at a relatively high-level, without detail, in order to avoid unnecessarily obscuring aspects of the present teachings.

The present teaching relates to providing enriched content in response to a request for content, which can be any form of content such as a news article, movie review, blog entry, word processing document, or any other textual material accessible through a medium such as the Internet or a private network. However, based on certain aspects relating to the content, the user requesting the content, and the platform upon which the content is to be presented, certain additional content may be retrieved and integrated with the requested content to create an enriched content viewing experience for the requesting user. As discussed in more detail below, the additional content may be from any number of sources and is selected based on its relatedness to a number of factors to be most relevant to the user when viewing the requested content.

Additional novel features will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following and the accompanying drawings or may be learned by production or operation of the examples. The novel features of the present teachings may be realized and attained by practice or use of various aspects of the methodologies, instrumentalities and combinations set forth in the detailed examples discussed below.

In FIG. 1(a), a typical presentation of content intended for certain platforms such as a mobile platform may generally be of a minimal format. When viewed on such a platform, only the minimal amounts of content are typically displayed. For example, as shown in FIG. 1(a), an article 101-1 is presented on the display of platform 100-1 which may be a mobile device. This article 101-1 contains a heading 111-1, body text 112-1, and links 113-1 to photos relating to the article 101-1. As shown in FIG. 1(a), typically only text is displayed and the formatting of the heading 111-1 and body text 112-1 of the requested content is made to best fit on a small screen of a mobile platform. Moreover, photos or other media such as videos that might be relevant to the requested content are typically included as text-based links 113-1 and may not be resolved into images when the page is first loaded, but only after the user selects such link.

Such a minimalist view is often ideal for users of mobile platforms simply because there is not enough space on the display of a hand-held device to show much more than text. The convenience of accessing such mobile-specific content tends to come at the cost of the viewing experience to the user.

In FIG. 1(b), a presentation of content is shown on a platform 101-2 in accordance with an embodiment of the present teaching. Platform 101-2 may be a graphic display of a larger size than a mobile device platform for which the requested content was intended. Such a platform 101-2 could be, for example, a monitor connected to a desktop computer, a home entertainment center, or even a tablet computer. In any of these examples, the display platform may be less-restrictive than the mobile platform for which the requested content was intended. As shown in FIG. 1(b) the requested content 110-2 is presented in the center region of the graphic display of the platform 101-2, with a heading 111-2, body text 112-2, and photos 113-2. Although similar to the requested content on the mobile platform in FIG. 1(a), the requested content in FIG. 1(b) may take advantage of, for example, the larger display size, faster processing speed, and greater bandwidth and may be enriched in terms of the font sizes of the heading 111-2 and body text 112-2, and the photos 113-2 may be downloaded, rendered, and embedded into the body text 112-2.

In addition to the requested content presented 110-2, additional content is presented to the user of platform 101-2. For example, a region 102-2 located at the top of the content page may be used to present information to the user that is, for example, related to the user account. For example, the user may be accessing the requested content 110-2 through the user's Yahoo! home page and the top portion of the display 102-2 may be the Yahoo! banner information, which provides to the user access to content through, for example, a search engine command line. In addition, region 121-2 located to the left of the requested content 110-2 may, for example, present to the user access to content relating the user's personal accounts. For example, if a user links her accounts to an enriched content provider, region 121-2 may display links to and/or portions of the user's personal content such as email, documents, twitter, and content from other social media accounts that relate to the requested content. Further, to the right of the requested content 110-2, the region(s) 131-2, 132-2, and 133-2 may contain places where additional content is presented, which is related to the requested content 110-2. One exemplary configuration is where in the top region 131-2, there are headings and links to content that is determined to be related to the requested content 110-2 such as, for example, news articles that are covering the same topic as the requested content. Also in this exemplary configuration, in region 132-2, there may be headings and links to comments made on one or more social media sites relating to the topic of the requested content. Finally, in the region 133-2 there may be one or more targeted advertisements that have some relevance to the requested content.

In addition, the additional content is specific to the user at that particular instant. As discussed further below, the identification of the additional content may be based on the content that the user initially requested, the user's location and other demographic information, the user's other accounts and social media connections, the user's selected preferences, and the user's interests based on past activities. Additional content associated with any and all of these items may be presented to the user as a part of an enriched content display and provide to the user quickly-accessible links to other related content.

Of course, FIG. 1(b) is exemplary only and there is no specific arrangement or size of the regions presenting the requested content or the additional content. In one embodiment, the user is given the ability to select the quantity, locations, content types, and sizes of the regions that are presented. As shown in FIG. 1(b) a user may be able to select and modify the parameters of each region to create a customized portal page. In an alternative embodiment, the service through which the user is requesting the content may determine how and where at least some additional content is displayed with the requested content 110-2. For example, the content provider may choose to have certain regions designated for displaying one or more advertisements.

FIG. 2 is a high level depiction of an exemplary system 200 in which an enriched content generator 260 is deployed to provide additional content, according to a first application embodiment of the present teaching. The exemplary system 200 includes users 210, a network 220, a search engine 230, content sources 240, user database 250, the enriched content generator 260, an ad server 265, an ad database 270, a content parser 280, and a base station 290. The network 220 in system 200 can be a single network or a combination of different networks. For example, a network can be a local area network (LAN), a wide area network (WAN), a public network, a private network, a proprietary network, a Public Telephone Switched Network (PSTN), the Internet, a wireless network, a virtual network, or any combination thereof. A network may also include various network access points, e.g., wired or wireless access points such as one or more base stations 290 or Internet exchange points through which a data source may connect to the network 220 in order to transmit information via the network 220.

Users 210 may be of different types such as users connected to the network via desktop connections (210-4), users connecting to the network via wireless connections such as through a laptop (210-3), a handheld device (210-1), a wearable device such as glasses, goggles, or a helmet (not shown), or a built-in device in a motor vehicle (210-2). From a device 210, a user may send a request for content via the network 220 and receive the requested content through the network 220.

The target of the user's content query can vary. In one exemplary embodiment, the user sends a content query via the network 220 to the search engine 230. In one embodiment, the user accesses the search engine 230 by an interface such as a webpage presented on the user device 210 and connected to network 220. The search engine 230 may access content sources 240, among other sources, through the network 220 to locate and return a search result in response to the user's content query. The search engine 230 may also access the enriched content generator 260 directly or through the network 220 to provide additional content for presentation to the user in certain circumstances such as when the requested content is of a more restrictive, minimal format, e.g., a mobile-specific format, and the user device 210 has, e.g., a larger display. The enriched content generator 260 may in turn seek additional content by searching for it through the search engine 230, requesting it through the ad server 265, or accessing it in the user database 250 or the contend sources 240. In another exemplary embodiment, the user sends the content query directly to the enriched content generator 260 via the network 220. Similarly, the user may access the enriched content generator 260 directly by a user interface such as a web page presented on the user device 210. In such an embodiment, the user's content request to the enriched content generator 260 may initiate one or more search queries with the search engine 230 to locate the requested content as well as any additional content to integrate with the requested content to create an enriched content page to present to the user.

In either of the above-mentioned embodiments, the content parser 280 may also be used as a part of a response for a request for content to parse content into content components for purposes of locating additional content, and/or integrating additional content with the requested content. Of course, depending on the system architecture, the content parser 280 may exist as a subcomponent of either or both the search engine 230 and enriched content generator 260 or be accessible over the network 220, as depicted in FIG. 2.

The content sources 240 include multiple content sources 240-1, 240-2, . . . , 240-n. A content source may correspond to a web page host corresponding to an entity, whether an individual, a business, or an organization such as USPTO.gov, a content provider such as cnn.com and Yahoo.com, or a content feed source such as Twitter or blogs. Both the search engine 230 and the enriched content generator 260 may access information from any of the content sources 240-1, 240-2, . . . 240-n, and rely on such information to respond to a query (e.g., the search engine 230 identifies content related to keywords in the query and returns the result to a user) or provide additional content relating to the requested content. The enriched content generator 260 may also access additional information, via the network 220, stored in the user database 250, which may contain, e.g., information about a user's preferences as well as content provided by ad server 265.

The information in the user database 250 may be generated by one or more different applications (not shown), which may be running on the search engine 230, at the backend of the search engine 230, or as a completely stand-alone system capable of connecting to the network 220, accessing information from different sources, analyzing the information, generating structured information, and storing such generated information in the user database 250. Such information can be state information such as cookies, or structured information, giving weight to certain categories of content that the user or other similar users tend to find of interest. One example of this is the generation of a user's preferences based on the user's past activities. When a user is presented with requested content and the additional content, observations of the user's course of actions with respect to the additional content may be used to better-tailor selections and presentation of subsequent additional content. This feedback enables the system, for example, to learn the interests of the user.

The user database 250 may contain information relating to a population of users. The enriched content generator 260, for example, or a separate engine or agent (not shown), may access this information to find similarities among users in order to locate content in response to a request for content. For example, when User A seeks information relating to, say, movies playing in local theatres and subsequently access content relating to reviews on movies currently in theatres, then when User B access content relating to movies playing in local theatres the enriched content generator 260 or other object would attribute some weight to content relating to movie reviews when ranking the additional content presented to User B. Moreover, when 100 users request content relating to, for example, local movies playing and 90 of the 100 subsequently access content relating to the latest James Bond movie, then enriched content generator 260 or other object would attribute weight to content relating to the latest James Bond movie when ranking the additional content presented to a user requesting content relating to local movies plating. In addition, each request for content that a user executes may be compared to other users to create loose groups or clusters of similar users, and the enriched content generator 260 may take into account the interests of other users in a group or cluster when determining what items to include as additional content and how to rank such content.

FIG. 3 is a flowchart of an exemplary process in which a content enrichment server operates to provide enriched content, according to an embodiment of the present teaching. In this embodiment, a request for content is received at 310. This request may be directed to and/or serviced by a search engine, an enriched content generator, or even a separate server specifically configured to handle such requests. In any case, such a device may operate an interface with which a user may interact including entering a request for content. The request may be a general request for content such as the latest new headlines on CNN.com or a specific request for content such as a specific news article or a particular URL. In response to the request for content, the device parameters are obtained at 320. Such device parameters may include the display settings, the browser window size, and the availability of certain browser plug-ins. A page of the requested content is obtained at 330. To obtain the requested content page, the content enrichment server locates the content by its own mechanisms or by employing a search engine, the selection of which may depend upon whether the requested content is locally accessible or whether the content is available remotely through the Internet. When the page is obtained, whether the page was created for a specific platform is determined at 340. In order to make this determination, additional sub-steps may include scanning and/or rendering the requested content page for any indicators that it is, for example, mobile specific. If it is determined that the requested content is not created for the requesting device platform (e.g., a desktop computer requesting content that was created specifically for a mobile platform), then, at 350, additional content is identified. The identification of additional content, as described in more detail in the description of FIG. 4, may depend on any number of factors, including but not limited to the subject matter of the requested content or the user's preferences, as may be determined by the user's affirmative selections, search history, social medial connections, or preferences of other users that are deemed related to the user in one or more ways (social media connection (e.g., a follower on Twitter), a contact, or just another user who has similar interests). From any of these sources, additional content may be identified and categorized in one or more categories (e.g., news article, advertisement, tweet, etc.).

At 350 the identified content is also ranked in an order that is most relevant to the user. However, in the case of advertisements or other revenue-generating content, the ranking may be weighted on the basis of revenue, i.e., the income generated when the user clicks on the advertisement or other content. The amount of additional content identified may be determined by the additional space available on the browser or display of the requesting user's device. For example, if the requested content would take up only 50% of the useable space and each additional content is allocated 10% of the space, then five items of additional content may be identified. Next, at 360, the additional content is integrated with the requested content page. This integration may be performed in a number of ways, such as by including links to the additional content in a separate area along side of the requested content. Another format may be that the additional content is embedded within the requested content, such as making certain words in the requested content into hyperlinks to the additional content or, for example, placing small advertisements in line with the text of the requested content and predetermined intervals (such as every ten lines of text). The end result is that an enriched page is generated containing the requested content and additional content. Further details of integrating additional content with the requested content page are discussed below with respect to FIGS. 9-12. Finally, at 370, the page is transmitted to the user in response to the request. 370 is also the action that is taken when it is determined, at 340, that the requested content is created for the device platform requesting the content. Alternatively, or in addition, at 340, the requested content page may be parsed into its components whether or not it was intended for the platform of the requesting user. This enables the process to retain the relevant portions of the request for content and continue through the process of obtaining additional content.

FIG. 4 depicts the inputs and outputs of an enriched content generator 400, according to an embodiment of the present teaching. When it is determined that additional content is to be presented, the enriched content generator 400 receives information relating to the requested content (such as the request for content or parsed data from the requested content), the data from a user (such as user account information like subscriptions and memberships), and platform information (such as browser size). In analyzing the input content/information, the enriched content generator 400 draws from media sources available from the Internet 401, social medial sites 402, user account data 403 associated with the requesting user as well as other users, and advertisement databases 404 to identify related material to the requested content and the user's preferences and supply the related material as an output.

To illustrate this process, take the example of a user request for content relating to skiing in Aspen, Colo. When the system receives such a request for content, it may follow the process outlined in FIG. 3. When it is determined that additional content may be presented, the enriched content generator 400 may review all or part of (parsed) the requested content and the user data to determine where to retrieve the additional content. Based on this information, the enriched content generator 400 may identify related articles on the Internet 401 that are related to the requested content such as ski resorts in Aspen (e.g., web pages to ski resorts, weather reports, etc.). However, because the enriched content generator 400 may also access social media 402 content relating to the user, the enriched content generator 400 may be able to identify (and attribute a higher ranking weight to) ski resorts in Aspen that were also visited by social connections of the user. For example, perhaps a social connection of the user visited Aspen last season and “checked in” to Snowmass Ski Resort and posted photographs of the trip. Each of these related social media items may potentially be used as additional content to present to the user. Other related content might be identified by reviewing other user accounts 403 who also searched for skiing in Aspen, Colo. Moreover, a related advertisement may be generated from ad database 404 for inclusion as additional content having some relationship to the user's social media connections (e.g., the particular hotel that the user's social media connection stayed at when visiting Aspen, or the type of powder skis the connection purchased last season). Finally, the additional content may be the user's personal information, such as information relating to the user's itinerary for her upcoming ski trip to Aspen.

FIG. 5 depicts the input and outputs of a content parser 500, according to an embodiment of the present teaching. When requested to parse a requested page, the content parser 500 takes the content of the identified page and separates each component of the content into a separate item. As mentioned before, the content parser 500 may be a separate agent or may be an integrated function of a search engine or the enriched content generator 400. As shown in FIG. 5, the content parser 500 retrieves or receives a requested page and outputs the various components of the requested page, such as the text, images, links, and even ads. The content parser 500 may serve to parse content for at least two purposes: 1) to parse the requested content into components for identifying related content, and 2) to parse content into components for integrating and presenting enriched content to the user.

FIG. 6 is a flowchart of an exemplary process in which a content enrichment server may operate tasks in parallel to provide enriched content, according to an embodiment of the present teaching. In this process, a request for content may be received from the user, at 600. The system may, in parallel, obtain platform parameters, at 601, retrieve requested content, at 611, and determine the user's momentary interests, at 621. The system may obtain relevant user information at 620 for determining the user's momentary interest. The system may parse the requested content into components, at 612. The parsing may provide information relating to whether the requested content was intended for a particular platform, such as, a mobile platform. The obtained platform parameters and requested content information may be compared and it may determine whether additional content is to be requested, in step 613. If so, the process may identify additional content, at 614. Additional content relating to the user's interests may also be obtained, at 622. When the system has obtained the platform parameters, additional content relating to the requested content, and additional content relating to the user's momentary interests, the layout of the content may be determined, at 630. The layout determination may take into account the platform parameters (i.e., the available area to present content) and the relevance of each additional content item with respect to factors of relevance discussed previously. The enriched content may then be generated, at 631, and transmitted to the user, at 632. In addition, the system may learn of the user's preferences and customize its subsequent enriched content by following the user's subsequent navigation information, at 633. This navigation information may be collected and subsequently used to determine the user's momentary interest, at 621.

FIG. 7 is a flowchart of an exemplary process in which a client requesting content receives enriched content, according to an embodiment of the present teaching. In this process, a content request is received from a user of the client, at 701. The parameters relating to the user platform are obtained, at 702, and then transmitted with the request to the server, at 703. Subsequently, the enriched content is received by the client from the server, at 704. As discussed above, the enriched content contains both the requested content as well as additional content relating to the requested content and the user. The received content (requested and additional) is then presented to the user, at 705. As the user navigates the requested content and additional content, the client receives this information, at 706, and transmits it to the server, at 707, so that the server may incorporate the user's navigation information in subsequent determinations of additional content.

FIG. 8 is a functional block diagram of an exemplary system 800 in which a request for content may return an enriched content page. Each or some of the blocks in the system 800 may be a stand-alone computer or server connected to the Internet and/or a local area network while others may be subroutines within one or more programs operating on a single computer or server. In this system, a request handling unit 810 may initially receive a request for content. Depending on certain conditions, such as for example, system demands, time of day, geographic location of requestor, preferences selected by the requestor, or type of request, the request handling unit 810 may for example deny the request, redirect the request, or queue the request. A parameter handling unit 811 may obtain parameters related to the platform on which the requested content to be presented. The parameters may include information related to the user device and information related to the network through which the enriched content page is transmitted. For example, the parameters include device and network capacities, e.g., screen resolution, display type, network bandwidth, latency, etc.

Under some conditions, the request handling unit 810 may send a request to an initial content generator 820 for generating initial content. Depending on the manner of the request and the parameters, if any, set by the requesting user, the initial content generator 820 may do any number of things in response to the request. For example, in response to certain requests received by the initial content generator 820 from the request handling unit 810, the initial content generator 820 may send a request for content to a content retrieving unit 830. This request sent to the content retrieving unit 830 may be identical to the incoming request for content that was received by the request handling unit 810. Upon receiving the request for content, the content retrieving unit 830 may retrieve the content from one or more content sources 840 or, in some embodiments, the content retrieving 830 unit may cache some content that, for example, may be commonly requested. The retrieved content may contain information relating to the type of platform upon which the page was intended to be viewed (e.g., a mobile device). Upon retrieving the requested content, the content retrieving unit 830 may then forward the retrieved content to the initial content generator 820.

Upon receiving the requested content, the initial content generator 820 may do a number of things sequentially or simultaneously. The initial content generator 820 may send the requested content to a content parser 850 to parse the requested content into different components such as text, images, headings, advertisements, etc. The content parser 850 may be able to parse the requested content based on typical HTML organization but also based on heuristics or other known methods. The content parser 850 may then return some or all of the content to the initial content generator 820 where it may be forwarded to a content page generator 890. The content parser 850 may also forward or indicate to an enriched content generator 870 certain information such as the type of information was requested by the request for content.

The initial content generator 820 may also forward some or all of the requested content it received from the content retrieving unit 830. What may be forwarded to the content page generator 890 from the initial content generator 820 may be dependent upon the information provided by a platform assessment unit 812. For example, the platform assessment unit 812 may indicate to the initial content generator 820 that platform of the device upon which the request was sent may be a desktop computer with a browser window open at a size of 1680×1050 pixels while the content retrieving unit 830 sent to the initial content generator 820 content that was designed for a mobile device having a browser window of 960×640. In such circumstance, the initial content generator 820 may send the parsed text of a requested content to the content page generator 890 as well as embedded photos or videos in a larger size (area and/or resolution).

The initial content generator 820 may also forward or indicate to a content subject analyzer 860 the requested content it received from the content retrieving unit 830. The content subject analyzer 860 analyzes the requested content for a multitude of things such as for example the type of content (e.g., news, information, photo, audio, video, etc.), the subject matter of the content, the temporal significance of the content (i.e., a historical request or a recent news event). The content subject analyzer 860 may then send certain search terms and other information to the enriched content generator 870 for determining what type of and how to prioritize additional content to include into the enriched content page.

Upon receiving information from the content subject analyzer 860, the enriched content generator 870 may send a request to the content retrieving unit 830 to retrieve enriched content. Upon receiving the requested content from the content retrieving unit 830, the enriched content generator 870 may forward the content to an enriched content ranking module 880 where the enriched content is ranked according to its relevance to the terms identified by the content subject analyzer 860. In some embodiments, the enriched content may also be sent to the content parser 850 to be parsed and returned to the enriched content generator 870 in various parts. Upon receiving and ranking the enriched content, an enriched content ranking module 880 sends the ranked additional content to a content page generator 890. Upon receiving the requested content from the initial content generator 820 and the ranked additional content from the enriched content ranking module 880, the content page generator 890 combines the contents into one page to be viewed by the requesting user.

FIG. 9 is an exemplary functional block diagram of a content page generator, according to an embodiment of the present teaching. In this embodiment, the content page generator 890 generates the enriched content page by arranging candidate additional content items according to a page layout in an optimized manner through a multiple-phase selection process, thereby increasing the chance that the user will engage with the enriched content page. The content page generator 890 in this embodiment includes a template layout filtering unit 902, a content module filtering unit 904, an additional content matching unit 906, a user engagement estimator 908, and a page layout optimizer 910.

The template layout filtering unit 902 in this embodiment is configured to select one or more template layouts of the enriched content page based on parameters associated with the user device or network. For example, parameters of the device capabilities and the network capabilities are received from the parameter handling unit 811, and are used as a basis for filtering all the possible template layouts stored in a template layout database 912 into a reduced set. This filtering selection is account for parameters such as resolution, user input characteristics (e.g. touch enabled), bandwidth, and latency. Each template layout is associated with its own parameters such as page type, dimension, suitable resolution, file size, etc. By comparing the parameters of each template layout in the template layout database 912 against the parameters of the user device or network, unfitted template layouts are filtered away. Out of the filtering phase, the template layout filtering unit 902 outputs a short-list of layouts that reference all the available slots on the user interface (across all selected templates). Each user interface slot may be described in terms of user interface real estate (e.g. position and dimensions). In one example, a search results page template layout stored in the template layout database 912 may include a header slot with a search box, a north slot where sponsored search ads reside, an algo slot for algo web search, an east slot for ads, a south slot for ads, and a tail slot for navigation. Each slot is associated with a position on the page layout and a dimension. The north slot, or the sponsored ads slot, is for example 1024×250 pixels.

As described above, the enriched content generator 870 may obtain additional content items based on user information and/or the initial requested content. In one example, personalized additional content items are identified and retrieved by the enriched content generator 870 based on information associated with the user, such as, user profile, user online activities, and user online content consumption pattern. In another example, additional content items are selected from content related to the topic/subject of the initial requested content. In this embodiment, each additional content item has a content type, such as, for example, “search ads,” “product listings,” “named entities,” “news stories,” etc. Also, each additional content item has a position-independent user engagement metric, whose value indicates a degree of engagement between users and the particular content item. The user engagement metric may be, for example, click-through-rate (CTR), dwell time, advertisement conversion rate, or any other suitable metric as known in the art. Although the actual value of the user engagement metric may depend on the position on the content enriched page (i.e., which slot the particular content item is assigned to), the position dependency may not be considered during the additional content selection phase in this embodiment.

The content module filtering unit 904 in this embodiment is configured to filter available content modules stored in a content module database 914 based on the filtered template layouts from the template layout filtering unit 902 and/or the additional content items provided by the enriched content generator 870. Each available content module stored in the content module database 914 is associated with one or more types of content items and dimensions. In one example, sponsored search ads module can render web search results type of content items and is in a dimension from “800×” to “1240×” pixels. In another example, a graphical module can show product listing ads or display ads. The graphical module may support content types of both products and large rectangle (LREC) display. The graphical module may render in the dimension of “300×250” pixels. In still another example, a super graphical module can render a person's Wikipedia card. In this embodiment, candidate content modules, as retrieved from the content module database 914 of available modules, are filtered based on the slots presented on the template layouts selected by the template layout filtering unit 902 and/or based on the additional content items provided by the enriched content generator 870. For example, if the provided additional content items do not have a certain type of content, then the content module(s) associated with the type of content are filtered away. In another example, if the dimension of a content module cannot fit into any available slots in the selected template layouts, then such content module is filtered away as well.

The additional content matching unit 906 in this embodiment matches all the possible candidates from the template layout filtering unit 902, content module filtering unit 904, and the enriched content generator 870 to combine content items, content modules, and layouts (i.e., creating triplet combinations of [layout, module, content]). For example, if the remaining content modules are super graphical and Sponsored Search and the two available slots on the selected template layout are north and south slots, then two triplet combinations of the layout-module-content set may be created: the sponsored search results in the north slot and the super graphical in the south slot; and the opposite combination switching positions. In this embodiment, there may be more than one candidate content item per slot. All the possible triplet combinations may be created for future consideration.

As the available slots on the enriched content page are limited, selection may be made from all the additional content items provided by the enriched content generator 870. In one example, as described above, additional content items may be ranked by the enriched content ranking module 880 based on their relevance with respect to the intent of the user inferred from the topic/subject of the initial requested content and the user profile. Thus, the selection may take such ranking into account. In this embodiment, as each additional content item is associated with a content module based on the content type, candidate content items may be filtered away if their corresponding content modules do not exist (e.g., have been filtered away by the content module filtering unit 904). In some embodiments, the value of user engagement metric of each content item may be another factor in selecting the additional content items from all additional content items provided by the enriched content generator 870. For example, additional content items with low CTR are less likely to be selected.

In this embodiment, the selection of the most suitable layout-module-content triplet combination from the candidate combinations is done by the user engagement estimator 908 in conjunction with the page layout optimizer 910. As described above, each content item is associated with a position-independent user engagement metric. Once a candidate content item is assigned to a slot with a position on the template layout, the user engagement estimator 908 may estimate a value of user engagement metric for the particular content item on the particular slot (i.e., position dependent user engagement score) based on a user engagement prediction model 916. The model 916 may be trained and optimized by a model training unit 918 based on, for example, a pre-defined objective function. This objective function may be determined based on the specific user engagement metric, e.g., CTR, dwell time, or advertisement conversion rate. In one example, CTR is estimated based on calculating the probability of click given a user, a list of content items, a set of content modules, and a layout, as clicks over views aged over time. The estimated probability of click is then assumed to be a good predictor of the expected CTR. In order to have sufficient availability of clicks and views (impressions), the model 916 exposes the triplet combinations, initially randomly, and exploits certain combinations as the CTR starts to trend up compared with the random exploration.

Based on the scores of user engagement metric of each triplet combination, the page layout optimizer 910 may determine the desired triplet combination and assign the additional content items to corresponding slots based on the desired triplet combination. In one example, an overall score of user engagement metric with respect to the enriched content page may be used as a basis for determining the desired triplet combination. The triplet combination that has the highest overall score of user engagement metric of the enriched content page is then selected, i.e. across the experience, and not just one link at the time. In the case of CTR, the final selection may be optimizing the layout of the page for overall “CTR welfare.”

It is noted that in some embodiments, not only the placement of additional content items is optimized by the user engagement estimator 908 and the page layout optimizer 910, the placement of the initial requested content may also be optimized. In one example, if the layout of the enriched content page has a slot specifically reserved for the initial requested content, then the initial requested content is assigned to that slot. In another example, if the layout has two or more slots available for the initial requested content or does not specify any slot for the initial requested content, then the placement of the initial requested content may be optimized in the similar way as the additional content items.

FIG. 10 depicts exemplary template layouts, content modules, and content items, according to an embodiment of the present teaching. A template layout may be predefined with multiple slots on it, each of which is to be assigned with a content item. A template layout may be used for a particular type of page, such as a search results page, a portal page, an e-commerce page, a social media page, etc. Each slot on a template layout is defined by user interface real estate, e.g., position and dimensions. In some embodiments, some of the slots may be specified to be assigned to a particular type of content on the enriched content page, e.g., the initial requested content being in the middle slot (slot 5).

A content module may be predefined by properties, e.g., module type, associated content type, and dimensions. Module types may be, for example, sponsored search ads module, graphical module, super graphical module, etc. A sponsored search ads module may render content type of web search results, and a graphical module may support content types of products and LREC display. Each content module is also associated with a suitable dimension or range of dimensions. For example, the sponsored search ads module may be from “800×” to “1024×” pixels, and the graphical module may be rendered in a “300×250” pixels area. The associated content type and dimension may be used as factors to filter and select content modules as described above with respect to FIG. 9.

A content item has its content type, such as product listings, search results, advertisement, etc., and a user engagement metric value, which indicates the level of engagement between users and the content item. Based on the various properties associated with the template layouts, content modules, and content items, respectively, triplet combinations may be determined from the selected template layout(s), content module(s), and content item(s). In one example, content type is a property associated with both content modules and content items and thus, may be used to filter or combine content modules and content items. In another example, dimension is associated with both templates layout (slots) and content modules and thus, may be used to filter or combine template layouts (slots) and content modules. In still another example, the actual user engagement metric value is affected by the position and/or dimension of the slot to which the content item is assigned. Thus, the combination of content items with template layouts (slots) may also take into account of the user engagement metric values.

FIG. 11 is a flowchart of an exemplary process of providing an enriched content page, according to an embodiment of the present teaching. At 1102, a user request for content is received. As discussed above, the initial requested content may be intended to be presented on a platform (e.g., a mobile device) that is more restrictive than the platform (e.g., a desktop computer or a laptop computer) on which the content is actually to be presented. At 1104, parameters related to the platform on which the content is actually to be presented are obtained. The parameters may include information related to the user device and/or the network, such as but not limited to screen resolution, bandwidth, latency, display types, etc. Additionally or optionally, information related to the user from which the request is received may be also obtained for content personalization purpose. At 1106, additional content items are obtained. The additional content items may be personalized for the user or related to the topic of the initial requested content. The page layout and content modules may not be considered in obtaining the additional content items at 1106. At 1108, a layout of the enriched content page is determined based on platform-related parameters obtained at 1104. One or more parameters, e.g., screen resolution, display type, network condition, etc., may be used as factors to filter away unfitted template layouts. At 1110, some of the additional items are assigned to slots on the determined layout. These additional content items may be selected from all the additional content items obtained at 1106 by matching with content modules and layout as discussed above. The assignment of the selected additional content items to page layout slots may be determined based on the user engagement metric. For example, the assignment is determined such that the overall user engagement metric value of the enriched content page is optimized. At 1112, the enriched content page including the initial requested content and the additional content items arranged in accordance with the page layout is transmitted as a response to the request.

FIG. 12 is a flowchart of another exemplary process of providing an enriched content page, according to an embodiment of the present teaching. In this embodiment, a multi-phrase selection process for determining the suitable triplet combination is disclosed. At 1202, available template layouts are filtered based on the device and/or network capacities. At 1204, candidate content items related to the user and/or the initial requested content are identified. At 1206, content modules are filtered based on filtered template layouts obtained at 1202 and candidate content items obtained at 1204. At 1208, all possible candidate layout-module-content sets (triplet combinations) are generated. At 1210, values of user engagement metric for each candidate layout-module-content set are calculated. Based on the calculated values, at 1212, one layout-module-content set is selected for the content enriched page to be presented to the user.

To implement the present teaching, computer hardware platforms may be used as the hardware platform(s) for one or more of the elements described herein. The hardware elements, operating systems and programming languages of such computers are conventional in nature, and it is presumed that those skilled in the art are adequately familiar therewith to adapt those technologies to implement the DCP processing essentially as described herein. A computer with user interface elements may be used to implement a personal computer (PC) or other type of work station or terminal device, although a computer may also act as a server if appropriately programmed. It is believed that those skilled in the art are familiar with the structure, programming and general operation of such computer equipment and as a result the drawings should be self-explanatory.

FIG. 13 depicts a general computer architecture on which the present teaching can be implemented and has a functional block diagram illustration of a computer hardware platform which includes user interface elements. The computer may be a general purpose computer or a special purpose computer. This computer 1300 can be used to implement any components of the enriched content generation as described herein. For example, the enriched content generator 400 of FIG. 4 and the content page generator 890 in FIG. 9 can be implemented on a computer such as computer 1300, via its hardware, software program, firmware, or a combination thereof. Although only one such computer is shown, for convenience, the computer functions relating to content enrichment may be implemented in a distributed fashion on a number of similar platforms, to distribute the processing load.

The computer 1300, for example, includes COM ports 1350 connected to and from a network connected thereto to facilitate data communications. The computer 1300 also includes a central processing unit (CPU) 1320, in the form of one or more processors, for executing program instructions. The exemplary computer platform includes an internal communication bus 1310, program storage and data storage of different forms, e.g., disk 1370, read only memory (ROM) 1330, or random access memory (RAM) 1340, for various data files to be processed and/or communicated by the computer, as well as possibly program instructions to be executed by the CPU. The computer 1300 also includes an I/O component 1360, supporting input/output flows between the computer and other components therein such as user interface elements 1380. The computer 1300 may also receive programming and data via network communications.

FIG. 14 depicts a general mobile device architecture on which the present teaching can be implemented. In this example, the user device on which enriched content is presented is a mobile device 1400, including but is not limited to, a smart phone, a tablet, a music player, a handled gaming console, a global positioning system (GPS) receiver. The mobile device 1400 in this example includes one or more central processing units (CPUs) 1402, one or more graphic processing units (GPUs) 1404, a display 1406, a memory 1408, a communication platform 1410, such as a wireless communication module, storage 1412, and one or more input/output (I/O) devices 1414. Any other suitable component, such as but not limited to a system bus or a controller (not shown), may also be included in the mobile device 1400. As shown in FIG. 14, a mobile operating system 1416, e.g., iOS, Android, Windows Phone, etc., and one or more applications 1418 may be loaded into the memory 1408 from the storage 1412 in order to be executed by the CPU 1402. The applications 1418 may include a browser or any other suitable mobile apps for receiving and rendering enriched content stream on the mobile device 1400. Execution of the applications 1418 may cause the mobile device 1400 to perform the processing as described above. For example, the display of enriched content to the user may be made by the GPU 1404 in conjunction with the display 1406. User interactions with the enriched content may be achieved via the I/O devices 1414 and provided to the enriched content generator via the communication platform 1410.

Hence, aspects of the methods of providing enriched content to a user platform based on the requested content and the user platform, as outlined above, may be embodied in programming. Program aspects of the technology may be thought of as “products” or “articles of manufacture” typically in the form of executable code and/or associated data that is carried on or embodied in a type of machine readable medium. Tangible non-transitory “storage” type media include any or all of the memory or other storage for the computers, processors or the like, or associated modules thereof, such as various semiconductor memories, tape drives, disk drives and the like, which may provide storage at any time for the software programming.

All or portions of the software may at times be communicated through a network such as the Internet or various other telecommunication networks. Such communications, for example, may enable loading of the software from one computer or processor into another, for example, from a user device into the hardware platform(s) of a computing environment or other system implementing a computing environment or similar functionalities in connection with providing enriched content to a user platform based on the requested content and the user platform. Thus, another type of media that may bear the software elements includes optical, electrical and electromagnetic waves, such as used across physical interfaces between local devices, through wired and optical landline networks and over various air-links. The physical elements that carry such waves, such as wired or wireless links, optical links or the like, also may be considered as media bearing the software. As used herein, unless restricted to tangible “storage” media, terms such as computer or machine “readable medium” refer to any medium that participates in providing instructions to a processor for execution.

Hence, a machine readable medium may take many forms, including but not limited to, a tangible storage medium, a carrier wave medium or physical transmission medium. Non-volatile storage media include, for example, optical or magnetic disks, such as any of the storage devices in any computer(s) or the like, which may be used to implement the system or any of its components as shown in the drawings. Volatile storage media include dynamic memory, such as a main memory of such a computer platform. Tangible transmission media include coaxial cables; copper wire and fiber optics, including the wires that form a bus within a computer system. Carrier-wave transmission media can take the form of electric or electromagnetic signals, or acoustic or light waves such as those generated during radio frequency (RF) and infrared (IR) data communications. Common forms of computer-readable media therefore include for example: a floppy disk, a flexible disk, hard disk, magnetic tape, any other magnetic medium, a CD-ROM, DVD or DVD-ROM, any other optical medium, punch cards paper tape, any other physical storage medium with patterns of holes, a RAM, a PROM and EPROM, a FLASH-EPROM, any other memory chip or cartridge, a carrier wave transporting data or instructions, cables or links transporting such a carrier wave, or any other medium from which a computer can read programming code and/or data. Many of these forms of computer readable media may be involved in carrying one or more sequences of one or more instructions to a processor for execution.

Those skilled in the art will recognize that the present teachings are amenable to a variety of modifications and/or enhancements. For example, although the implementation of various components described above may be embodied in a hardware device, it can also be implemented as a software only solution—e.g., an installation on an existing server. In addition, the system and its components as disclosed herein can be implemented as a firmware, firmware/software combination, firmware/hardware combination, or a hardware/firmware/software combination.

While the foregoing has described what are considered to be the best mode and/or other examples, it is understood that various modifications may be made therein and that the subject matter disclosed herein may be implemented in various forms and examples, and that the teachings may be applied in numerous applications, only some of which have been described herein.
